Sometimes things (thoughts) happen ‘under the radar’.
There is a lot of talk about people not being as rational as they think they are. Soon we’ll learn to accept that we are not even as conscious of our thinking process as we presume to be.
The same kind of mental ‘ingrained’ habits are responsible for many men (and women) not accepting, deep in their hearts/minds, that men and women are ‘equal’ (I’d rather use equivalent instead of equal but this is another matter)
